I did self-pay and my doctor is about 2 miles from my house! (Looking forward to actually walking or biking there when it warms up!) I paid $15,300, and it was worth every penny. (that also includes a year's worth of fills & appointments) I've seen it advertised cheaper - especially in Mexico, but I'd much rather pay a bit more and have my doctor convenient for fills, questions, & support.
Writing the check was hard - but we took it from long term savings, and I knew if I kept going the way I was - I wouldn't be around in the "long term".
I'd pick a doctor you feel comforable with and who is close to you anyday over a savings of a few thousand. Good luck!!
